Endometriosis Concepts is focused on endometriosis history, concepts, theory and education. The Endometriosis Concepts and Theories summary begins about 1,855 BC and moves forward to Rokitansky's 1860 histology and Russell's 1899 recognition of non-visualized, intra-ovarian lesions of what Sampson would subsequently (1925) call endometriosis. Sampson also discussed venous dissemination (1918), epithelial metaplasia (1921), implantation from menstruating ovaries (1921), and retrograde menstruation (1927). Ongoing research in endometriosis includes more than 26,000 articles in PubMed (NIH), 291,000 array- and sequence-based data in the GEO database (NIH), and other information in non-NIH linked sources. Twenty-five references published in 2018 and 2019 are included in the Endometriosis Concepts and Theories summary. There are also introductions to the "tomato effect" and "reversal in evidence-based medicine."
